The Internal DAC is much better than you think - give'em a try! Before spending 1000EUR you shold probably go for an Instrument shop and look for an ESI Dr. DAC or if you want an high grade ADC spare an RME ADI-2

Zitat:

A USB interface will need a driver. Getting that into the Linux kernel will not be easy.

Give the Hifidelio's own DAC a try. A whole lot of people consider it really good.

Apart from that: A USB interface will need a driver. Getting that into the Linux kernel will not be easy.

The Hifidelio's own DAC is good enough for most people but some of us (including myself) are that crazy that they always want to achieve the best possible soundquality.

The idea to get audio output through one of the USB ports is attractive and if someone can make such a modification I would be very interested and even want to pay you a fair share for development! So if anyone thinks he is capable of developing such a mod, please let me know!

I do not know if you can use a USB DAC with the Hifidelio, not without additional software anyway, but Hifidelio's own built-in DAC is probably better than any available USB DAC. If the sound does not satisfy you, try to find a good second hand external DAC like "woonboot" did, or buy a reasonably priced new one like I did (AudioNemesis DC-1 for 500,- Euro).

(Or you can send in your Hifidelio for the VM modification, 700,- Euro.)

I know, and the soundquality of the Hifidelio is very good, but I am interested in the new active AVI speakers with build-in DAC and USB input, see http://www.avihifi.com. This would be a very nice combination with my fidelio..I like my AVI speakers for some years now and I think those new ones will sound better (real active), and the used Burr Brown DACs are certainly an upgrade to the used DACs in the fidelio.

When it comes to the powersupply, I'm using the one that comes along with the Apple iPod (12V). The reason for this was pure lazyness. Next step is to find a nice small box for the DAC and a different PWS.
